基于串口实现DSP程序的在线编程

On-line Programming of DSP Systems Based on Serial Port

目前DSP处理器普遍使用Flash作为其程序代码存储器,通过DSP的JTAG仿真接口对Flash存储器进行编程实现代码的更新,这给DSP系统的软件维护和升级造成了很大的困难。本文提出基于DSP设备的串口实现DSP程序在线编程的方法,使DSP代码的更新可以脱离仿真器,改善了DSP设备的易用性、可维护性,增强了DSP系统的技术生命力。

The software upgrade of Digital Signal Processor （DSP） systems which use Flash as program storage area commonly, is done by programming Flash through JTAG interface. But it brings about great inconvenience for software maintenance and upgrade. This paper proposes a new solution for on-line programming based on DSP with serial port, so that DSP code can be updated without emulator. This method brings many conveniences, which enhance the technique vitality of DSP systems , to the software maintenance and upgrade of the DSP systems.
